Inspired by a charm from the 1960s, each Calendar pendant is completely custom made. Tell us the month, day and year of a meaningful date for you, and we will have it minted it in 10 karat gold and mark it with a diamond, or birthstone of your choice. A completely modern heirloom. Perfect for a mom or a grandma...the new "mommy" necklace. The month featured is the actual month from the specified year.
